Ultrasonic Pulsed Doppler (USPD): A Novel Ultrasonic Method for Characterizing Suspensions of Nanoparticles

Africk S.A., Colton C.K., Prodyne Corp., US

This paper describes a novel means for particle characterization, the Ultrasonic Pulsed Doppler (USPD) system. This system uses a single transducer to measure ultrasonic backscatter from moving particles to perform measurements of particle concentration, size [...]

An Embedded Atom Method for Alloy Nanoparticles

Shan B., Hyun J., Wang L., Yang S., Kapur N., Nicholas J.B., Nanostellar Inc., US

We present the development and application of a high-accuracy embedded atom method (EAM) potential for the simulation of metal alloy nanoparticles. The potential was parametrized by a large set of density functional theory (DFT) calculations [...]

Non-destructive 3D Imaging of Nano-structures with Multi-scale X-ray Microscopy

Wang S., Lau S.H., Tkachuk A., Druewer F., Chang H., Feser M., Yun W., Xradia, Inc., US

X-ray microscopy offers a unique combination of large penetration depth, high resolution, and high sensitivity to elemental composition. When combined with computed tomography (CT) techniques, the full three-dimensional structure of a sample can be obtained [...]

NanoZeolites – porous nanomaterials for cleantech, encapsulation and triggered release applications

Daniell W., Sauer J., Kohl A., NanoScape AG, DE

Recent advances in hydrothermal synthesis techniques and procedures to modify the surfaces of the particles have led to the development of a new class of material – the NanoZeolites. The availability of porous, nanocrystalline materials [...]

Nanoscaled Mg(OH)2 Used as Flame Retardant Additive

Zhou B., Zhou Z., Wu Z., Fransson M., Zhou B., Zhou Z., Headwaters Technology Innovation LLC, US

Headwaters Technology Innovation (HTI) has applied aqueous colloidal chemistry with great success in the development of “bottom-up” nanomaterials and nanotechnologies. One such material is a nano-scaled magnesium hydroxide, NxCat® Mg(OH)2, which is primarily used as [...]

Evaluation of Antibacterial Activities of Zinc Oxide-Titanium Dioxide Nanocomposites Prepared by Sol-Gel Method

Chang H., Leung H., Nanyang Polytechnic, SG

Antibacterial activity of ceramic powders has attracted attention as a new technique that can substitute for conventional methods using organic agents. Ceramic powders of zinc oxide (ZnO), calcium oxide (CaO) and magnesium oxide (MgO) were [...]

Molecular approach for the synthesis of supported nanoparticles on active carbon using noble metal clusters

Willocq C., Vidick D., Hermans S., Delcorte A., Bertrand P., Dubois V., Devillers M., Université catholique de Louvain, BE

A molecular approach was envisaged for the preparation of nanoparticles supported on carbon. The support was first treated in order to build suitable anchors for organometallic compounds on the surface. Palladium clusters of various nuclearities [...]

Towards Nanoscaled Systems: New Dispersing Technologies

Fischer L., Scheid S., Thomas C., Serendip AG, CH

The presentation will give an overview of state-of-the-art technologies and today’s possibilities as well as technical and regulatory limitations. The focus will be on the potential of a new generation of homogenizers, which allowfor the [...]

Self-Assembly of Polymers and NanoParticles in Personal Care Products

Berg M.C., Suddaby N.A., Soane D., Soane Labs, US

Soane Labs develops and applies nanotechnology and advanced polymer chemistry to the personal care industry trough novel colorants and high-affinity polymers. By controlling the spontaneous self-assembly of polymers and nanoparticles at interfaces, the color, look, [...]

Toughening mechanisms of nanoparticle-modified epoxy polymers

Mohammed R.D., Johnsen B.B., Kinloch A.J., Taylor A.C., Sprenger S., The University of Trinidad and Tobago, TT

An epoxy resin, cured with an anhydride, has been modified by the addition of silica nanoparticles. The particles were introduced via a sol-gel technique which gave a very well-dispersed phase of nanosilica particles which were [...]
